Option to change bpm in iPhone/iPad IDJ app

I am a fitness instructor and would like to use the iPad / iPhone IDJ app for creating my mixes.

I currently own and mix my classes using MIXMEISTER successfully.

The iPad / iPhone app restricts changing the bpm of tracks, so that they can only be used at their original tempo. When creating a music mix for a class, this renders the app ineffective because I need to be able to control the bpm so the tempo doesn't suddenly slow / quicken randomly. The other point is that not being able to adjust bpm restricts my creativity as I am limited to working with tracks at certain bpm's and can't get as creative as I can wit MIXMEISTER.

Can you rectify this so that I can mix my classes whilst on the go on both my devices.
